feat(h6): AgentOps hardening — live alerting, provider-API reconcile, hosted dashboard, window breaker (79→80)

Browse Source 
Close the three gaps the scoring report itself flagged for H6 plus V15,
each as a real MVP + fail-able adversarial test (same pattern that lifted H5):

- D1 alert-dispatch.sh: alerts POST to a real HTTP webhook (severity routing,
  dedup window, retry) + dead-letter queue with redelivery; fail-loud in strict.
  Wired into agent-metrics.sh so a failing step pages live end-to-end.
- D2 provider-usage-fetch.sh + telemetry-reconcile.sh: pull usage from a provider
  usage HTTP API (all-or-nothing schema gate, fail-loud) + reconcile local vs
  provider ground truth — token under-reporting/hidden runs => TELEMETRY_DISCREPANCY.
- D3 dashboard-serve.sh + dashboard-server.py: serve the dashboard over HTTP with
  a stale-aware /healthz probe (fresh=200 ok, telemetry silent-death=503 stale).
- D4 circuit-breaker-check.sh: sliding-window failure-rate breaker (V15) — interleaved
  successes no longer evade the consecutive-failure breaker (CIRCUIT_OPEN_WINDOW).

New suite phase-h6-agentops-tests.sh: 20/20, all live against local HTTP endpoints
(webhook sink, mock provider API, dashboard server) — deterministic, no model needed.

Also fix sign-policy-bundle.sh key-sync invariant: the local-fallback branch only
exported policy-public.pem when generating a NEW key, so a Vault-DOWN run after a
Vault-signed run verified a local-key signature against the Vault pubkey (RSA padding
error, run-casan4 died mid-suite). Now always re-exports the pubkey before signing —
same fix class as tool-audit-lib.sh / governance-check.sh.

Full battery re-run sequentially: 175/175 PASS, 0 FAIL across 8 suites
(KMS SKIP this run — Vault down; validated live 2026-07-04). Docs synced:
scoring-run-report (H6 79→80, no harness below 80, 155→175), CASAN_HARDENING_STATUS
(Phase 5 D1–D4), Plan-07, submission README, and run-hardening.sh (H6+ scenes HO1–HO4).

## 4. Honest claim
Track A + Track C-MVP + Evidence Pack + H5 governance-hardening raise H4/H5/H6 from
"PoC/demo (~3.0/5)" to **early internal-production hardening**, with executable
adversarial tests for every control (155 checks, 0 fail — last full run 2026-07-04,
KMS validated live via Vault). Fair maturity score (`00_SUBMISSION_PACKAGE/evidence/
scoring-run-report.md`): per-harness **~80/100**, **H5 76→80** (approval-identity +
KMS live + WORM), so the **lowest harness is now H6=79** (was H5=76) — CASAN **Level 4**,
proven by attack. This is **not** full production readiness: serious production still
needs live IdP (OIDC/JWT), a true WORM store (S3 Object Lock), KMS-by-default + HSM,
true sandbox isolation, multilingual detection, and hosted telemetry — the [partial]/
[planned] rows above and in `CASAN_PLAN_07_PRODUCTION_HARDENING.md`.
